Installation In general Congratulations on your new WIKING woodburning stove. We are pleased that you have cho- sen a WIKING woodburning stove and confident that it will give you much pleasure. To ensure optimum operation and safety, we recommend that the installation should be carried out by an authorised WIKING retailer or a fitter recommended by the retailer. For an overview of WIKING retailers, visit www.wiking.com under “Retailer locations”. Safety The installation of your WIKING woodburning stove must always comply with all European, national and local building regulations. The installation must be carried out in accordance with the instructions in the installation and user manuals and subsequently registered with the local authorities. Upon installation, the chimney sweep must approve the installation before you can start using the woodburning stove. All WIKING woodburning stove packaging material must be handled in accordance with local waste management regulations. Room requirements Always ensure a supply of fresh combustion air to the room where the stove is to be installed. The woodburning stove uses approx. 7-16 m3 of air per hour. A window that can be opened or an adjustable air valve will be sufficient. It must not be possible to block the adjustable air valve/grate. In newly built/airtight dwellings, we recommend that a fresh air system should be installed for the direct supply of external air to the combustion. This fresh-air system may be bought separately. Before installing the stove, you must ensure that the load-bearing capacity of the floor can withstand the weight of the stove and the chimney. The weight of the chimney should be cal- culated according to its dimensions and height.

WIKING Mini with a base and WIKING Mini with short legs must not be mounted on combustible floors. It is still considered a combustible floor even if an ember catching, non-combustible floor plate is placed on top of the combustible floor. A non-combustible structure under WIKING Mini with a base and low legs must extend at least 400 mm in front of the stove.

Remember to pay attention to the applicable regulations concerning the required distance between the wall and smoke pipe. Please be aware that not all glass parts are heat-resistant. For this reason, a glass wall should sometimes be treated as a combustible wall, in which case we ask you to contact your local chimney sweep or glass producer to hear at what distance the stove should be kept from glass. Requirements for chimney and smoke pipe The height of the chimney must ensure sufficient draught and prevent any smoke nuisance. As a general rule, satisfactory draught conditions are achieved if the chimney is 4 m above the stove and at least 80 cm above the ridge. If the chimney is placed at side walls, the top of the chimney should always be higher than the ridge or the tallest point of the roof. Always be aware of any national and/or local regulations applying to thatched roofs and the location of the chimneys.r. The woodburning stove requires a minimum draught of 12 Pa (measured at EN 13240 mea- surement point). If measured just above the smoke flue socket, the chimney draught must be 18-20 Pa. The chimney must have a minimum clearing of Ø 125 mm or Ø 150 mm. The chimney must be provided with an easily accessible cleaning door. The chimney and flue duct must be of flue class T400 and be CE marked. Furthermore, it must have obtained the classification of G in soot fire testing. The required distance to combustible material must be complied with in ac- cordance with the brand label. Ask your WIKING retailer for further information. Changing the Smoke Outlet from Top Outlet to Back Outlet Proceed as follows to change the smoke outlet from top outlet to rear outlet: 1. Lift the top plate off the stove. 2. Remove the smoke ring on the top of the stove by unscrewing the three screws and lifting it off. 3. There is a cut-out for the flue duct in the back plate. Break off the plate within this cut-out to make a hole that the flue duct can fit into. 4. Remove the cover plate on the back of the stove by unscrewing the three screws (Torx Bit no. 30) and lifting it off. 5. Install the cover plate on top of the stove with the three screws. 6. Place the smoke ring in the smoke outlet hole in the back of the stove and secure it with the three screws. 7. Replace the top plate on the stove. A top cover can be bought as an accessory to cover the hole in the top plate of the stove if the stove is connected to a rear smoke outlet. A top cover can be bought as an accessory to cover the hole in the top plate of the stove if the stove is connected to a back smoke outlet. Connection to chimney All the stoves have both back and top smoke outlet that can be connected to an approved steel chimney on top or directly out at the rear to a chimney. Make sure that the chimney is tight and that no false draft is caused around neither the cover plate, in connection with a covered smoke outlet, nor the cleanout door and pipe connections. Please note that bent and/or horizontal smoke pipes will reduce the effect of the chimney draft.

Bottom plate 7. Protection during transportation 8. Fittings Please note: The combustion chamber is covered with plates made of vermiculite, which is a heat-insulating material. These plates ensure that the optimal combustion temperature is quickly reached, and they must therefore remain inside in the wood-burning stove. The steel smoke deflector and the vermiculite smoke deflector ensure that the passage of smoke through the stove is as long as possible, so that the flue gasses have more time to emit their warmth within the stove and the surrounding area. In this way you get more warmth from the wood you add to the stove, as the warm smoke is not simply sent out through the chimney. Fitting the loose parts Before the stove is installed, you must ensure that all loose parts are fitted correctly. Check that all insulation plates of the combustion chamber have been properly placed, i.e. that the bottom plate is horizontal and that the side plates are vertical and reach all the way up to the steel sides of the combustion chamber and down to the bottom plate. Vertical cross-section of the stoves (drawing A) 1. The steel baffle plate (1) is hung from two hooks and equipped with two pins (7) that serve as protection during transportation. Remember to remove the two pins before you start us- ing the stove. 2. The vermiculite smoke deflector (2) plate must rest on the two fittings (8) at the top and front of the combustion chamber and must be pushed as far back as possible into the combus- tion chamber. 3. The rear plate (3) must be pushed all the way back in the combustion chamber. 4. The cast iron bottom plate (6) should lie flat in the bottom of the combustion chamber. Chimney The chimney is the “engine” of the stove and it is crucial for the functioning of the woodburning stove. The chimney draft provides a partial vacuum in the stove. This vacuum removes the smoke from the stove, sucks air through the dampers for the so-called glass pane rinse which keeps the glass free of soot, and sucks in air through both primary and secondary dampers for the combustion. The chimney draft is created by the differences in temperature inside and outside the chimney. The higher the temperature within the chimney, the greater the draft. It is crucial, therefore, that the chimney is warmed up properly before closing the damper and limiting the combustion in the stove (a brick chimney takes longer to warm up than a steel chimney). On days where the wea- ther and wind conditions create insufficient draught inside the chimney, it is even more important to warm up the chimney as quickly as possible. The trick is to quickly get some flames going. Split the wood into extra fine pieces, use an extra firelighter, etc.

If the stove has not been used for a longer period, it is important to check that the chimney pipe is not blocked. t is possible to connect several devices to the same chimney. However, it is important to first check the applicable rules. Chimney sweeping To prevent the risk of chimney fires, the chimney must be cleaned every year. The flue duct and the smoke chamber above the baffle plate must be cleaned together with the chimney. If the chimney is too tall to be cleaned from above, it must be equipped with a soot door. In case of a chimney fire, close all dampers and call the firefighters. Before any further use, have the chimney checked by the chimney sweeper.

Firing manual - wood Your first heating session The lacquer will be fully hardened after the stove has been used, and the door and the ashpan should be opened very carefully as there will otherwise be a risk that the gaskets will stick to the lacquer. In addition the lacquer may initially give off an unpleasant odour, so make sure that the room is well ventilated. Warning: The accompanying glove may wear the surface paint off. Be careful not to touch the varnished surfaces the first two to three times you light the fire. Even after the paint has hardened, repeated use of the glove may wear the surface paint off. Tips about fuel Approved fuel types The wood burning stove is EN approved for combustion of wood only. It is recommended to use dried chopped wood with a water content of a maximum of 18%. Stoking a fire with wet wood results in soot, environmental problems, and a less efficient fuel economy. Recommended wood types All types of wood, for instance birch, beech, oak, elm, ash, conifers, and fruit trees can be used as fuel in your insert. The great difference is not in the fuel value, but in the weight of the wood types per cubic metre. Beech weighs more per m3 of wood than common spruce, for instance. This is why more common spruce is required, in terms of volume, to obtain an amount of heat similar to that of beech. Heavy types of wood such as ash, beech, oak and elm are generally not that easy to light up. In addition, they burn more slowly and give off more embers. Light types of wood such as birch, maple, spruce and pine are more easy to light up. They burn faster and give off fewer ambers. You may therefore take advantage of the light types of wood for lighting and use the heavier types of wood to ensure a longer burning time.. Banned fuel types It is not allowed to stoke a fire with the following: printed matter, plywood, plastic, rubber, fluid fuels, and rubbish such as milk cartons, lacquered wood or impregnated wood and fossil fuels. The reason that you should not apply any of the above is that during combustion they develop substances that are health hazardous and harmful to the environment. These substances could also damage your wood burning stove and chimney, rendering the product warranty void. Storage of wood A moisture content of 12-18% is achieved by storing recently felled wood outdoors under a lean-to for at least one year, preferably 2 years. Wood stored indoors has a tendency to be- come too dry and combust too quickly. However, it might be advantageous to store fuel for lighting a fire indoors for a few days prior to use. It is recommended to purchase a wood moisture meter to continuously check that the firewood has the correct moisture content before using it for firing.Split the wood and measure the mois- ture content of the split surfaces. Recommended dimensions The dimensions of the fuel are important to good combustion. The dimensions should be as

Norsk follows: Fuel type Length in cm Diameter in cm Wood for kindling a fire (finely chopped) 16-28 2-4 Chopped wood 16-28 6-9 Using the Air Damper To achieve good combustion, which results in better heating efficiency, it is important to add the right amount of air to the fire. Air is regulated with a user-friendly, one-lever system that is located under the stove door; see drawing D. When lighting a cold stove and when fuellingwith new wood, the regulating lever must be pu- shed to the extreme left to give the fire maximum air supply. When the fire is burning well, the air supply can be gradually reduced by moving the regulating lever to the right. The fire will die out if the regulating lever is moved to the extreme right. This setting should only be used in the case of overheating, if there is a fire in the chimney and when the fire in the stove has been allowed to go out completely in connection with cleaning, for instance. Lighting the stove A successful combustion process requires that the wood is lit in the right way. A cold stove and a cold chimney challenge the combustion process. Be careful to make a good lighting with suitably dry wood, using kindling and lighting the fire in the top layers of kindling. It is important to achieve a high flue gas temperature quickly. Move the air control lever to the extreme left to fully open the air supply to the combustion chamber. Place two pieces of wood (4-7 cm in diameter) horizontally in the bottom of the combustion compartment (corresponding to 0.75-1 kg). Place 6-10 pieces of kindling (a total of about 1 kg) randomly on top. Place 2 firelighters between the top layer of kindling. Light up the fire-lighters and close the stove door. If condensation forms on the glass, keep the door ajar for a little while and close again. When all of the wood has caught fire, the air supply can be gradually reduced by moving the air control lever to the right until uniform, steady combustion is achieved. Important! The ash pan must not be opened during the lighting stage and must always be kept closed when the stove is lit or the WIKING® Automatic™ might be damaged. Only open the door when lighting the stove, refuelling it and cleaning it. Never leave a stove before there are lasting flames in the wood after firing! Stoking When there are no more visible yellow flames, and a right ember is there, you can fire again. The layer of embers is suitable when the pieces of wood begin to disintegrate and the bottom of the stove is covered by embers. Carefully open the door to prevent smoke and embers from esca- ping. Make sure that there is an opening in the ember layer down to the grate (preferably in the middle of the grate), so that air from the grate can easily pass through the embers to the wood. Place 2 pieces of chopped firewood (approx. 1-2 kg) on top of the embers. The firewood should not be stacked higher than the holes in the vermiculite back plate. If the firewood is stacked up past the holes, the air from the holes in the back plate will act as the

“initiator”, which is not the purpose of the air. Close the door again and fully open the air supply by moving the air control lever to the extreme left.When the wood has caught fire properly, the air supply can be gradually reduced by moving the air control lever to the right until uniform, steady combustion is achieved. The further to the right the air control lever is moved, the less heat the stove will give off. But it is important not to regulate the air supply below a level at which there are still visible flames and steady combustion. During combustion, the outer surfaces of the stove will become hot, and due care must therefore be shown. When burning is complete When the stove is not in use, turn the air control lever all the way to the right. Cleaning the glass We recommend wiping the glass after a fire. This is best done using a paper towel. Fuelling with coal or pet coke The stove is not approved to use coal or pet coke as a fuel.

Firing in general Rapid or fierce heat Rapid or fierce heat is obtained by burning many small pieces of wood. Maximum amounts of fuel: The maximum allowed amount of fuel per hour is: Wood: 2,4 kg If these limits are exceeded, the stove will no longer be covered by the factory guarantee, and it may also become damaged due to excessive heat, the glass may turn white, for example.. The stove has been approved for intermittent use. The EN test is performed with 2 logs, both with a length of 16 cm, cross-section approximately 7.5 x 7.5 cm placed in vermiculite back plate to door orientation. It is burned with the air control set to max (the control lever pushed all the way to the left). After three minutes, it is regulated down to 40% (control lever set slightly less than half way to the right). Typical re-firing interval Typical re-firing interval at nominal performance Wood: 45 min (1,0 kg) Prolonged burning time You achieve a long burning time if you burn a few, slightly larger pieces of wood (max. 1 kg per piece, and always 2 pieces). You can extend the burn time by further closing off the air when the flames are dying out. When stoking, adjust up for maximum air (control lever is moved fully to the left). When the wood is burning well, slowly adjust the air down (control lever is moved to the right). You should not regulate below the point where there are continuously large, visible flames from the wood. When the wood has burned about 20 minutes and the flames are not as active, the air intake can be adjusted further down. How to achieve the best combustion • Use clean and dry wood Wet wood results in inefficient combustion, plenty of smoke, and soot. Furthermore, the heat will dry the wood, not heat up the room. • The fire should only be stoked with a little wood at a time You achieve the best combustion by starting up a fire often and using only a little wood. If you use too much firewood, it will take some time before the temperature reaches a level where you achieve a good combustion. • Make sure there is the right amount of air You should also make sure that there is plenty of air – especially in the beginning - so the temperature in the wood burning stove climbs quickly. In this way the gasses and particles released during the combustion will be consumed by the fire. Otherwise they build up soot in the chimney (constituting a chimney fire risk) or will be released in a non-combusted state into the environment. The wrong amount of air supply creates inefficient combustion and a modest effect. • Don’t savour the fire during night time We advise against adding fire wood to your stove and reducing the air supply at night in an attempt to still have some embers left in the morning. If you do so, large amounts of hazardous smoke will be emitted, and your chimney will be exposed to unnecessarily large amounts of soot with the risk of a chimney fire.

Maintenance Cleaning Any maintenance of the stove should only be carried out when it is cold. Daily maintenance is limited to vacuum cleaning the stove externally, using the soft brush attachment. You can also dust the stove using a dry, soft cloth or brush. But remember, only when the stove is cold. Do not use water, spirit or any other kind of cleaner, as this will damage the lacquer. Once a year, the stove should be thoroughly serviced. The combustion chamber should be cleared of ashes and soot. The hinges and the closing hook must be greased with liquid cop- per fat spray (heat-resistant up to 1100°C). Lift the door approx. ½ cm and spray copper fat onto the hinge leaf. Service inspection Your stove should be given a thorough, preventive inspection once every two years. This includes: • Thorough cleaning of the stove. • Checking the spring in the WIKING® Automatic™. Replace if necessary. • Checking gaskets. Replace gaskets if they are not intact or are no longer soft. • Checking and/or replacing insulation material. • Checking the combustion chamber base. • Use copper grease for hinges and locking hooks All service checks must be performed by an authorised fitter. Use only original spare parts. Inside cleaning Before chimney sweeping can be performed, the air control lever must be set to its minimum position to prevent soot and ash from entering the WIKING® Automatic™. Unless the safety fittings for transportation (2 split pins) have not already been removed, start by removing the split pins (drawing A, 7). First remove ash and soot from the combustion chamber. In drawing C you can see which plates are found inside the combustion chamber. Carefully remove the vermiculite plates, one after the other, in the following sequence: 1. Smoke deflector (top plate) 2. Rear plate 3. Left corner plate 4. Right corner plate 5. Left side plate 6. Right side plate After cleaning, carefully put the vermiculite plates back in place in the reverse order starting with the rear plate. Ashes It is easiest to empty the ash pan by pulling a plastic bag over it, turning it upside down and then carefully removing it from the bag. Ashes are disposed of via the domestic waste col- lection. Please note that there may be embers in the ashes for up to 24 hours after the fire has gone out!

Insulation The efficient, but porous insulation of the combustion chamber may, in time, be worn and da- maged. Cracks in the insulation are irrelevant to the efficiency of the stove. A crack in the back plate can cause secondary air to become incorrectly distributed in the combustion chamber, and it should therefore be replaced. However, it should be replaced, if there are actual holes due to parts of the lining falling off or when, due to wear and tear, it has been reduced to less than half its original thickness. WIKING® Automatic™ (drawing D1-D3) The spring in the WIKING Automatic™ should be controlled at least once every second year. Lift the top plate off the stove. Remove the two screws (1) in the top of both side plates. Re- move both side plates. Remove the rear plate of the stove (2). On a cold stove, the starting point of the feeler is controlled. The starting point on a cold stove is about 100 above horizontal. It should feel easy going and bouncy when you push it, no matter if the stove is cold or hot. Mount the rear plate, the side plates and the top plate again. Door/glass A sooty glass door can easily be cleaned with a piece of moist kitchen roll dipped in ash. Go about it in vertical movements (up and down). Follow up with a dry piece of kitchen roll. You should also ensure that air gaps in the door frame are free of ash and soot particles. Seals Check frequently to ensure that seals in the door and ash pan are intact and not brittle. Failing this, they should be replaced. Use original seals only. Surface Usually, it is not necessary to any treatment to the painted surfaces of the wood-burning stove. Any damage to the paint may, however, be remedied with spray paint, which can be bought from your stove retailer. Guarantee The guarantee does not cover damage due to insufficient maintenance!

Trouble Shooting If you experience that your wood-burning stove is not functioning optimally, consult this table to find some usual problems that may arise and how to solve them. If you cannot solve them and/ or other problems occur, pleas contact your maintenance man or wood-burning stove dealer. Problem Possible Cause Try the Following I cannot make a sufficient fire in the stove. Incorrect lighting. Further information: See the section on lighting and firing the stove. Poor chimney draft. Ensure that the smoke pipe or chimney is not blocked. Ensure that the chimney height is correct in relation to its surroundings. The glass pane is covered in soot. The wood is too moist. Only fire with firewood that has dried for at least 12 months beneath a covered shed and with a water content of 12-18%. A seal in the door is loose. The seals should be soft and flexible. If they are not, replace them. New seals can be purchased from your local wood-burning stove dealer. Insufficient supply of secondary air to the pane-flushing system. Move the air control lever further to the left. The temperature inside the stove is too low. Put more wood in the stove and move the regulating lever further to the left. Smoke enters the room when I open the door. The damper in the chimney is closed. Open the damper. Poor chimney draft. Ensure that the smoke pipe or chimney is not blocked. Ensure that the chimney height is correct in relation to its surroundings. The firewood is in flames. Never open the door if the firewood is in flames. The fire-proof materials in the combustion chamber are blackened after firing. You have not fired enough, i.e., there is not enough air or firewood. Move the air control lever further to the left. Moreover, igniting a larger quantity of wood might be needed. Combustion is uncontrollable. A seal in the door or ash drawer is loose. The seals should be soft and flexible. If they are not, replace them. New seals can be purchased from your local wood-burning stove dealer. Excess chimney draft. Close the damper in the chimney a bit at a time until the problem is solved. At the same time, move the air control lever further to the right. The door is not com- pletely sealed. Close the door completely. If it cannot close completely, it must be replaced with an original spare part.
